    What is 0.01µm ultrafiltration?

    It could block impurities larger than 0.01µm — for cleaner, better-tasting water.

    Will it take up a lot of space?

    Not at all. The slim WD-TSU-W housing fits neatly against your cabinet side — freeing up storage while delivering a steady supply of pure water.

    Does it waste water or use electricity?

    No, the WD-TSU-W generates no wastewater and runs on batteries — saving you money and shrinking your carbon footprint.

    How do I know when to change the filter?

    Front-panel indicator lights light up and beep when it's time.

    How easy is it to replace the filters?

    The twist-and-pull cartridges make replacements tool-free and leak-proof.
